Hello! First post here 
I´ve written a Macro that allows to pick a User and to display further information (position, hobbies, mobile number...). The information is afterwards displayed in a profile card. The profile card was made by piecing together different AUI elements. Besides the $param sections everything else is HTML / CSS.
It actually works great and looks good, except for the Profile Avatar, which is a cheap inclusion of the Profile Picture Macro.
<ac:structured-macro ac:name="profile-picture">
<ac:parameter ac:name="User">
$paramUsername
</ac:parameter>
</ac:structured-macro>This is handy because I don´t have to give up on the "follow" feature etc. thats available by mouseover, but I don´t quite understand how I can manipulate the picture format (increase size, round edges...).
How would you go about including the Avatar of the chosen User?
Thanks in advance for your input on this matter!
Cheers, Robin
